Thanks Rob. I have come up with a theory; I think the grain on the leather steering wheel makes my hands sweat more. Whenever I get in a car with a smooth leather (no grain), my hands don't sweat at all, like in the MKV GLI that we have. Any BMW with a grained leather wheel makes my hands sweat. It's strange. I have a feeling I may be re-wrapping my wheel (when it needs to be done years down the road) with smooth leather the next go-around.
